Exhausted Host

When Exhausted Host leaves the battlefield, create 4 1/1 black Shade creature tokens with Possess. (Whenever a creature with Possess attacks, you may attach it to a creature defending opponent controls instead of having it participate in combat. If you do, it becomes an Aura Enchantment with "Enchanted creature gets -1/-1." It becomes a creature again when the enchanted creature leaves the battlefield.)
